“There is an electoral campaign now and I believe that some terrorist groups hypothetically might be interested in destabilizing the situation in Russia before the elections. They might be interested in demonstrating that they are still active, that what government claims as victory in the Northern Caucasus is far from happening. And they also might be interested to undermine the international image of the Russian Federation because some of them are reportedly financed from international sources and they need to demonstrate to their sponsors that they still can inflict damage to Russia and its international image,” he said.
